This is getting to be just too much fun. I think Geoff was right, we
don't need to initialize sNum because we don't care if we go into
negative territory. And since the handler isn't actually using the value
of the line, we can omit passing it by removing "each". So it could be
even shorter/faster this way:
local sNum
function reverseText @pList
sort lines of pList numeric by reverseSort()
return pList
end reverseText
private function reverseSort
subtract 1 from sNum
return sNum
end reverseSort
I'm not sure the private declaration is necessary, but it won't hurt. My
thinking is that the engine only looks for a private function in the
current script, but it also looks in the current script first when the
function isn't private. If the function is there, it seems that the
speed would be the same in either case. The engine would stop looking at
the same place.
Passing the list with @ is a good addition.
Then there is Alex's version which is a different animal.

Hi Peter,
you also might want to check your reverse algorithm on 7.x.x
in my testing Jacque's initial post with little tweaks is as fast as your
code and faster on 7.x.x (tested on 7.0.2 rc2) In my testing it took only
60% of the time compared to yours on 7.x.x
Of course Alex Tweedly's ingenious inverse code leaves everything in the
dust, except on 7.x.x.

on mouseUp
put field 1 into tData
put the milliseconds into t
get reverseText (tData)
put the milliseconds - t into field "fRes"
put it into field 1
end mouseUp
local sNum
function reverseText @pList
put the number of lines in pList into sNum
sort lines of pList numeric by reverseSort(each)
return pList
end reverseText
private function reverseSort
subtract 1 from sNum
return sNum
end reverseSort
--------------------------------------------------------
private and @ help when the line count is high.
Kind regards
Bernd
